17 Claims.

This invention relates to machines for applying reinforcing material to insoles such as are used in the making of Welt shoes and particularly to machines for applying a strip of fabric such as duck or canvas to the inner face of the rib and to the insole adjacent to the rib. A machine of this type is disclosed in our Letters Patent of the United States No. 2,242,248, granted May 20, 1941.

Objects of this invention are to improve, simplify and render more convenient and efficient machines of this type. The machine disclosed in the above-mentioned patent comprises a strip guide, an applying roll movable into and out of operative position with respect to the insole and a spring-actuated finger which, as the applying roll approaches operative position, presses the strip against the applying roll, As illustrated herein, a finger operated in substantially the same manner as before is provided with a broad face to engage the portion of the strip which is applied to the body of the insole and press it against the applying roll, the said face being curved to correspond to the curvature of the applying roll and being provided with grooves in said face, the grooves being opposite to the pins or spurs on the applying roll so that if the spurs should extend through the strip they will extend into the grooves and not engage the face of the finger.

As in the machine of the prior patent, an outside guide is provided which engages the feather of the insole and the outer face of the rib and also an inside guide engaging the inner face of the rib. As illustrated herein, the inside guide is adjustably mounted on the finger above described which presses the strip against the applying roll. Thus, the inside guide is carried into operative position with respect to the inner face of the rib by the movement of the finger into operative position against the applying roll. The inside guide is adjustable heightwise with respect to the finger so that it may be set in accordance with the depth of the inside channel. As in the machine of the prior patent, upper and lower feed rolls are provided, the upper feed roll being movable toward the lower roll to engage the feather of the insole and cause it to be fed by rotation of the rolls. In the illustrated machine, the outside guide is formed on one end of a lever the fulcrum of which is at the rear of the machine and which lever between its ends is connected to the upper feed roll so that the outside guide is raised and lowered directly by movement of the upper feed roll into and out of operative position:

In the machine of the prior patent, shears are provided for cutting off the strip'the blades .5 of which are first moved bodily into position to embrace the strip and are then closed to cut off the strip. In the machine herein illustrated, shear blades operating in a similar manner are provided. The blades are arranged at an oblique angle to. the length of the strip so that the severed ends of the strip, instead of being square. are substantially mitered, it having been found that ends so cut may be laid over each other at the end of the toe and secured to the insole with- 15 out the necessity of applying additional cement where the strips overlap,

As in the machine of the prior patent, the illustrated machine is power driven and treadleoperated means is provided to set a clutch to start the machine, to move the upper feed roll into engagement with the insole, and to move the applying r011 from inoperative to operative position, the treadle being held depressed during a the operation of the machine. In the operation of the prior machine, it was found fatiguing to the operator to maintain the treadle depressed during operation of the machine throughout a days run and accordingly the illustrated machine is provided with mechanism for relieving the operator substantially of the effort required to hold the treadle depressed.

The illustrated machine is provided with a more effective electrical unit for heating the strip and with improved means for moving the strip toward the heating element and the heating element toward the strip prior to the strip-applying operation and for insuring movement of the heating unit out of the way of the applying mechanism as the latter moves to inoperative position.

These and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

The illustrated machine is in its general organization substantially similar to that disclosed in the above-mentioned patent to which reference may be had for a more complete description thereof.

Briefly described, the machine comprises a column II) on which is mounted a head plate I2 to which are secured two uprights I4, I5. In the uprights I4, I6 is journaled a shaft I8 carrying at its front end a lower feed roll 28 and at its rear end a pulley 22 which is driven by a belt 23 from an electric motor through a clutch which is controlled by a treadle rod 24. The shaft I8 carries a gear 26 meshing with a gear 28 on a shaft 30 which has an upper feed roll 32 secured thereto, the beveled portion of the feed roll being provided with blunt teeth to enhance its feeding action. The shaft 30 at its rear end is loosely journaled in the upright I4 and near its front end is journaled in a block 34 guided for vertical movement to enable the feed roll 32 to be raised and lowered. Also journaled in the uprights I4, I6 above the shaft 33 is a rockshaft 36. Near the rear end of the shaft 36 are secured two laterally projecting arms 38, 48, the arm 38 (Fig. 1) being connected by a link 42 through yielding mechanism to an operating rod 44 (Fig. 3) downward movement of which will rock the shaft 38 in a counterclockwise direction and move the arm upwardly. To the arm 48 (Fig. 2) is pivoted at 46 a rod 48 the lower end of which passes through a lug 58 carried by a lever 52 fulcrumed at 54 to the frame and pivotally connected at 56 to the block 34. On the rod 48 is a spring 58 resting at its lower end upon the lug 59 and engaged at its upper end by a nut 68 threaded on the rod 48. Check nuts 52 threaded on the lower end of the rod 48 engage the lug 58 at the proper time in the movement of the arm 48 to raise the rear end of the lever 52, thus moving downwardly the block 34 in which the shaft 38 has its bearing and pressing the upper feed wheel 39 against the work.

At its front end the rockshaft 3% is bent to form an arm 64 upon which the applying roll and other operating instrumentalities of the machine are mounted. Secured by screws 86 to the arm 64 is a plate 68 carrying a stud E8 on which are freely mounted independently rotatable spurred disks 12, I3 and I4. On the inner end of the stud II? is a head I6 which not only holds the spurred disks in place but serves to rub an upturned portion of the strip against the inner face of the insole lip, this rubbing action being produced by longitudinal movement of the shaft 36 in response to a spring E8 the action of which is controlled by a cam, as disclosed in our prior patent.

A strip S of reinforcing material such as Gem duck coated with pressure-responsive cement such as latex is led from a reel or supply of indefinite length over a pin extending between ears 82 mounted on the upper arm 84 of a bell crank lever pivoted at 86 and having an operating arm 88 through a hole in which a rod 80 passes. The rod 96 at its lower end is connected to an arm 92 fixed to the rockshaft 36. On the rod 9|] above the operating arm 88 is a fixed collar 94 and below it is a sliding collar 96 between which and a fixed collar 98 is a spring I00. The purpose of the mechanism just described will be later explained. From the pin 88 the strip S is led through a slit near the end of a Z-shaped guide member I92 the lower end of which is secured at I04 to the arm 92 and hence to the rockshaft 36. Between its ends the member I02 carries ears I86 to which is pivoted a leaf spring I08. A screw I I0 threaded through the member I02 bears against the spring and causes it to press upon the strip as it enters a lower strip guide I-I2. This guide :II2 (Fig. 5), as disclosed in our prior patent, is shaped to bend the rear marginal portion of the strip toward the right or toward the direction from which the insole is fed. The forwardly bent portion is then carried around an edge II3 formed on part of the guide H2 and brought into position parallel to the inner face of the rib against which it is pressed by the head IS. The remainder of the width of the strip engages the periphery of the head I8 and the peripheries of the three spurred disks I2, F3, I4 which constitute the applying roll and act to press the remainder of the strip against the body of the insole.

Each of the disks I2, I3, I4 is provided about its periphery with sharp spurs II4 which project beyond the disks an amount about equal to the thickness of the strip, the disks acting to control the application of the strip to the insole, as explained in our prior patent. In order to insure such control it is important that the strip be pressed throughout a substantial portion of its width against the spurs II4 after it comes in contact with the applying roll and before the applying roil presses the cemented face of the strip against a similarly cemented surface on theinsole. For this purpose a finger H6 is formed at its lower end with a surface I I I corresponding in curvature tothat of the disks I2, I3, I4 of the applying roll, which surface, as shown in Fig. 9, presses the strip against the applying roll except in the region of the points of the spurs II4, the pressing face II! of the finger being provided with grooves H8 which prevent dulling of the points of the spurs I I4 by contact with the pressing surface of the finger. The finger H6 is pivoted at I25] to a lug I22 secured to the arm 64 and has a portion I23 thereof extending above the pivot I28 and connected by a spring I24 to a pin I26 on the rockshaft 36. As heretofore, when the applying roll is moved out of its operative position, the finger H5 is automatically separated from the applying roll and when the applying roll is approaching its operative position the spring I24 becomes effective to press the finger IIB toward the applying roll to force the strip S upon the spurs H4.

In the illustrated machine a guide I28 (Fig. 8) to engage the inner face of the rib of an insole I is mounted on the finger I It by screws I32 which pass through openings in the plate I 30 larger than the screw and are threaded into the finger. The enlarged openings in the plate I30 enable the guide I28 to be adjusted both vertically with respect to the bottom of the inside channel and laterally with respect to the inner face of the insole rib. The lower portion of the plate I30 is bent toward the applying roll (Fig. '7) and has a portion I34 which has been bent double to provide a rounded surface at I28 (Fig. 8) which bears against the inner face of an insole rib to form the guide as there shown. The plate I30 is extended rearwardly to provide a flange I36 (Fig. 8) which engages a stationary lug I38 secured to the upright I6 (Fig. 2) As the arm 64 is swung clockwise with the shaft 36 to carry the applying roll out of operative position, the flange I36 engages the lug I38 which prevents it from swinging with the arm 64 but permits it to move heightwise, the flange I36 merely sliding upwardly on the lug I58. When the applying roll is swung downwardly into operative position, a reverse movement takes place, the finger descending with the applying roll as they mutually approach each other and finally being moved by the applying roll away from the lug I38 against the pressure of the spring I24, the strip being thus firmly pressed against and impaled by the spurs II4 before the applying roll reaches the insole. Relative approaching movement of the roll and finger is limited by engagement of a surface I40 (Fig. 1) on a portion of the plate I30 secured to the finger II6 with a corresponding surface on the arm 64 which carries the applying roll.

As in the prior machine, an outside guide I42 (Fig. 8) is provided to engage the outer face of the rib and the feather of the insole, this guide being moved downwardly into operative position in conjunction with the movement of the upper feed roll 42 toward the insole. In the illustrated machine the guide I42, as shown in Fig. 2, is formed on the front end of a bar I44 the rear end of which is pivoted at I46 to the upright I4 and an intermediate portion pivoted by a screw I48 to the block 34 so that as the block 34 is raised and lowered to move the feed roll toward and from the insole the guide I42 receives similar movements, its movement away from the insole being limited by a stop I48 on the upright I6.

As in the machine of our prior patent, shears are provided for cutting off the strip and, as illustrated herein, the blades of the shears are arranged at an angle to the strip so that they sever the strip obliquely, as illustrated in Fig. 5. The shearing mechanism comprises a slide I50 the front portion of which is bent upwardly at about 30 from the horizontal and forms a blade I52. The slide I56 is held by gibs I53 to a sup- I56 and bent to a position parallel with the slide I50. On top of the slide I50 is a shear-operating slide I60 mounted for movement in the same direction as the slide I50 and held in position by screws I62 passing through slots I64 in the slide I60 and threaded into the slide I50. The portion I58 is beveled as at I50 to enable it to clear the slide I60 as it turns about the angular axis I56. The slide I60 has an inclined slot I66 which is engaged by a barrel-shaped roll I6'I on a stud I68 secured to the rearward extension I58 of the shear blade I54 and extending above the slide I60. With this construction it will be seen that movement of the slide I60 to the right (Fig. 4) with respect to the slide I50 will cause actuation of the blade I54 to close the shears and sever the strip. Such movement, however, is initially prevented by a flap II0 having a straight edge III extending in the direction of the slide I60 and engaged by the upwardly projecting stud I68. Since the force applied to the slide I60, because of engagement of the stud I68 with the flap I'I0, cannot move the slide I60 relatively to the slide I50, both slides move together to translate the shears bodily to operative position. When that position is reached the slide I56 is arrested by engagement of a pin I'I2 projecting downwardly from the slide I with the front end of a slot I'I4 formed in the fixed supporting plate I55. When the pin I12 reaches the end of the slot I'M, however, the stud I68 is beyond the front end of the flap I'I0. Accordingly, the slide I may move relatively to the slide I50 and cause movement of the shear blade I54 relatively to the blade I52. The flap I10 is pivoted to fixed ears Il6 on an axis parallel to the direction of movement of the slide I60 and is yieldingly held in horizontal position by a leaf spring IlB bearing against a square edge of the flap adjacent to its pivot. When return movement of the slides I50, I60 occurs, the stud I68 moves under the front end of the flap I10 and then out from under it, whereupon the fiap drops again into its initial position when the slides I50, I60 have assumed their initial positions with respect to each other. Fig. 6 shows the flap H0 in section and the stud I68 at the time when it is moving rearwardly beneath the flap. Later the slot I66 will move the stud I68 to the right, causing it to engage a beveled surface I'I3 on the under side of the flap and lift the flap which falls back into its initial position when the stud I68 passes beyond the edge I'II.

To move the slides a rockshaft I82 (Fig. 2) has an upwardly extending arm I84 at the upper end of which is a slot I66 (Fig. 5) through which passes a screw I88 threaded into the slide I60. The arm I84 is moved in a direction to retract the slides by a tension spring I88 connected at one end to a screw I92 on the arm I84 and at the other end to the frame. The rockshaft I82 has an arm I94 (Fig. 1) connected to the armature I96 of a solenoid I88 so that when the solenoid is energized, for example, in the manner disclosed in our prior patent, the arm I84 will be moved to the right against the spring I80, thus actuating the slide I60 and causing operation of the shears in the manner already explained.

As shown in Figs. 1 and 5, an arm I99 is secured to one of the gibs I53 of the shear mechanism and extends in a direction substantially parallel with the shear blades, said arm carrying at its outer end a combined insole stop and strip-forming tool 20L The forming tool 26I (Fig. 1) projects toward the right from the arm I99 and has a flat lower face against which the bottom of the insole is brought when the strip is to be severed. The heightwise extent of the tool 20I corresponds to the heightwise extent of the insole rib and when the shears I52, I54 have been moved bodily into their operative position the lower shear blade I52 rests against the rear edge of the forming tool 26I or against a plate 203 which may be applied to the top of the tool. The right-hand edge of the plate 205 is preferably straight to hold the strip substantially flat and parallel to the cutting edge of the blade I52 at the point where it is being cut. The righthand end of the tool 20I has a formation adapted to force the strip into the angle between the inner face of the rib and the body of the insole, the end face of the tool being inclined to correspond substantially to the inward inclination of the rib and curved in plan to correspond more or less closely to the curve of the rib of a pointed toe.

The illustrated machine may be employed to practice the method disclosed in Letters Patent of the United States No. 2,255,353, granted September 9, 1941, in the name of S. M. Griswold, in which the reinforcing strip is laid along one side of the insole from toe to heel and then along the other side from heel to toe. After reaching the toe on the second side the operator allows the applying tool to swing upwardly, thus releasing the insole which he presents against the lower face of the forming tool 2M which is then beneath the applying roll in its upwardly swung position. The strip is now in the path of the shears which are operated to sever the strip at an inclination. The inclined end of the strip on the insole is formed into the angle between the rib and the body of the insole by pressing it againt the tool I and turning it in contact therewith. Since the strip at the beginning of the operation is cut at the same angle as the strip at the end of the operation, the inclined end of the second strip may be laid over upon the inclined end of the first strip and still have some portion of the cemented face adjacent to its end come in contact with the cement on the insole, the second end being thus secured over the first without the necessity of applying cement to the end of the strip first laid in order to hold the end of the second strip in place. Secured to the arm I99 and extending across the ends of the shear blades I52, I 54 is a guard plate 265 to prevent the operators hands from being placed accidentally in the path of the shears when they are operated. Since the shear blades are tilted upwardly, the forming tool 20! is located higher than in the machine of our prior patent, thus giving more space above the feed roll Zli and making it more convenient for the operator to present the insole against the forming tool Ziii.

Under some conditions a strip containing thermoplastic stiffening material is employed, in which case it is desired to heat the strip before its application to an insole. For this purpose a long electric heating element 256] is mounted on a member 2B2 pivoted at 2&4 to the back of a casing 286 and normally hangs in a vertical position against a stop being biased in that position by a tension spring 2238 connected at one end to the member 282 above its pivot 2M and at the other end to a part of the machine frame. Current is supplied from any suitable source through a flexible conductor 2H). When the rockshaft 36 is turned counterclockwise to carry the applying roll into operative position, the arm 92 (Fig. l) swings upwardly, causing the collar 96 to apply pressure through the spring [00 to the arm 88 which, turning about the pivot 86, swings the strip guide 3i! toward the heating element until a pin 2E2 extending between the ears 82 engages the heating element 2% above its pivot 2%, thus swinging it counterclockwise against the tension of the spring 2% until its lower portion engages the guide I02. This mutual approaching movement of the strip guide and the heating element locates a considerable length of the strip in a position parallel to the heating element and at a uniform short distance therefrom to cause the strip to be heated as it passes to the applying roll. The applying r011 may also be kept in heated condition by an electric heating element 2l4 mounted on the arm 64 and supplied with current through conductors 2|5 enclosed in a flexible casing 2 l6.

When the applying roll moves toward its inoperative position, the tension of the spring I00 is relieved and the spring 208 acts to wing the heating element 280 about the pivot 204 out of the way of the applying roll. If, however, the spring 208 should fail to act promptly, the mechanism carried by the arm 64 might engage the heating element 200 and cause damage thereto. Accordingly, means is provided for positively moving the heating element out of the way of said mechanism as the applying roll moves to inoperative position. For this purpose a curved arm 2|8 is secured at 220 to the member 202 and extends upwardly to present a surface 222 in position to engage an extension of the pin 8!] when the parts are in operative position, as shown in Fig. 1. Hence the clockwise movement of the applying roll mechanism to inoperative position first relieves pressure on the spring I00 and then causes the fixed collar 94 to engage the arm 88, causing positive clockwise movement of the arm 84 whereupon the pin 80, acting on the arm 2|8, positively moves the heating element 200 about its pivot 204 toward its vertical position out of the way of the mechanism carried by the arm 64. When suflicient movement of the heating element 200 has occurred to insure that the applying mechanism will clear its lower end, the upper end of the arm 2l8 has descended sufficiently, due to movement about the center 204, to permit the pin to swing across the upper end of the arm 218, thus permitting further movement of the arm 84 to carry the strip still farther away from the heating element, the heating element 200 and the strip S being thus separated sufficiently so that no substantial heating of the strip occurs when the parts are in inoperative position.

The operating rods 24, 44 (Fig. 3) are connected to a lever 224 fulcrumed at 226. If a treadle were connected directly to the front end of the lever 224, depression thereof to pull downwardly on the rods 24, 44 would, in bringing various operating instrumentalities of the machine into operativ position, place under tension several springs against which the operator would have to exert considerable efiort during continuous operation of the machine. To make it easier to operate the lever 224 and to hold it in depressed position, a toggle comprising link 221, 228 is pivoted at oneend to a lug 233 on the column If) and at the other end to the lever 224. The joint of the toggle is connected by a link 232 to an upright arm 234 of an angle lever pivoted at 236,-

the other arm 238 of the angle lever constituting a treadle. Depression of the treadle 238 causes the toggle to be moved from a bent position to a nearly straight position, thus causing depression of the front end of the lever 224 to bring the operating instrumentalities of the machine into operative position and to cause power operation thereof. Of course very little eifort is required to maintain the toggle in an almost straight position during operation of the machine.

In a machine for applying strip material to shoe parts, the combination of strip-supplying means, a strip-applying roll movable toward and from its operating point, means for holding a portion of the strip in extended condition between the supplying means and the ap-plying roll, manually operated means for moving the applying roll toward the operating point, a heating device, means acting as the applying roll approaches the operating point to move the heating device toward the extended portion of the strip, and means acting positively as the applying roll moves away from the operating point to restore the heating device to its initial position.

16. In a machine for applying a strip of material stiflened with thermoplastic material to the body of the insole to reinforce it, the combination of strip-laying means movable toward and from the insole, means for guiding the strip to the laying means, means for feeding the insole, strip-heating means pivoted to hang by gravity in a vertical plane, means for moving the striplaying means toward the insole and simultaneously effecting mutual movement between the heating means and the strip-guiding means to bring the strip and the heating means into proximity, and means acting positively to move the heating means toward its normal position during the early part of the movement of the applying means away from the insole.

17. In a machine for applying a reinforcing strip to a ribbed insole, means for advancing the insole past an-operating point, a freely rotatable applying roll movable into and out of operative position with respect to said operating point, an operating lever depressible to move the roll toward its operating point, a toggle connected between a fixed support and the lever, and a treadle lever connected to the joint of the toggle so that operation of the treadle lever straightens the toggle and depresses the operating lever.
